A hydraulic pipe marked as Scheduled 80 is extra heavy.
One disadvantage of employing hose in hydraulic systems instead of piping or
tubing is that it is less permanent.
What type of fitting should be used on a steel hydraulic line?
Pressure loss in a hydraulic line relies on the flow velocity.
Hydraulic lines should never be constructed with galvanized pipe.
Rotary valves have round cores.
To facilitate comparison, manufacturers rate the flow capacity of valves by their
ANSWER CV Factor.
Which of the following types of valves should be used in a hydraulic system to
change the cylinder's direction of motion? - ANSWER Directional control
valves
The construction of a spool valve causes it to -- Be p
artially balanced.
In applications using a needle valve that must be switched off often, a ________
should be employed - ANSWER seat.
, What property of a fluid does the word "specific gravity" describe? - ANSWER
Density
Cavitation refers to the production of big air bubbles or pockets in a hydraulic
system.
According to the Law of Energy Conservation, energy cannot be generated or
destroyed; instead, it can be transformed.
Bernoulli's Law Principle states that when fluid flow rises in a system, pressure
decreases.
What form of energy is generated in a hydraulic system when the piston raises
an object to a higher level? - ANSWER POTENTIAL
Fluid pressure in one portion of a hydraulic system is limited by a lowering
valve.
The flow from the exit of a sequence valve is at the line pressure.
A meter-out flow control valve is utilized to regulate fluid flow from the
ANSWER actuator.
The operational differential pressure of a relief valve is the difference between
its maximum and the cracking pressure.
